Based on the differential equations for 3D steady-state current conduction, the similarity criteria, which the similarity in the internal electric field of lithium-ion battery should be met, are derived by using dimension-less analysis, and the electric field similarity relationship between physical object and simulated object is determined. Finally a FE model for the electric field of lithium-ion battery with multi-layer structure is built with calculations performed by using ANASYS software, and the correctnesses of similarity criteria and relationship established are validated.
